Schema for representing resources for calendaring and scheduling
services

Abstract
This specification describes a schema for representing
resources for calendaring and scheduling. A resource in the
scheduling context is any shared entity that can be scheduled by a
calendar user, but does not control its own attendance status.

Internet-Draft Schema for Resources July 2010
1. Introduction
This specification defines a schema for representing
resources to ease the discovery and scheduling of resources between
any calendar client and server.
The Object model chosen is the lowest common denominator to
adapt for LDAP.
2. Conventions Used in This Document
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL
NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in
this document are to be interpreted as described in [RFC2119].
3. Resource Object
A resource object definition should contain all information
required to find and schedule the right resource. For this, it
should contain all, or a set of the attributes described in
Section 4. The cn attribute, described in Section 4.1 MUST be
present in any resource object. Additional proprietary attributes
may be defined as well, but must begin with "X-". Clients
encountering attributes they don't know about must ignore them.
This document specifies whether a given Attribute or Property is
required for a query to find the right resource, or is used to just
give additional information during scheduling of the resource.
Attributes or Properties required to contact the resource are not
included in this specification. LDAP attributes defined in
[RFC4519] and VCARD properties defined in vCard Format Specification
[I-D.ietf-vcarddav-vcardrev] can be used to include contact
information for the resource.
3.1. LDAP Resource ObjectClass Definition
In LDAP, a resource object SHOULD be defined as an objectclass
with attributes as defined in Section 4. This objectClass MUST be an
auxiliary class. Its Superior class is the calEntry objectClass as
defined in Section 2.4.3.1 of [RFC2739].
Definition of the CalendarResource ObjectClass:

6. Security Considerations
As this document only defines schema for representing resource
information for calendaring and scheduling and does not refer
to the actual storage mechanism itself, or the calendaring and
scheduling protocol, no special security considerations are
required as part of this document.
7. IANA Considerations
A new IANA token 'resource', that can be used as a value
representing a Resource in a VCard, as defined in
Section 4.2.2 needs to be registered. In addition, the
following new VCard Properties need to be registered by IANA.
